IMPROVEMENT IN WATER-ELEVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'

Be it known that I, G. W. DIcKERsoN, of Prairietown, in the county of Vigo, and State of Indiana, have invented a .new and useful Improvement in Water-Elevators; and I do hereby declare that thel following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to new and useful improvements in the method of raising water from wells and cisterne, and consists in the construction and arrangement of parts, as hereinafter described.

In the accompanying sheet of drawings- Figure 1 represents a side elevation of the apparatus partly in section.

Figure 2 is a top view.

Figure 3 is a vertical section of iig. 1, through the lline a: x.

Figure 4 shows the bucket detached.

Similarletters of reference indicate corresponding parts. y

A represents the well-curb.

B is the windlass-shaft.

G is the windlass, upon which the elevating-rope or chain is wound.

D is the bucket.

E is'the spout for discharging the water.

F is the elevating-rope.`

The windlass-shaft is supported by the curb, on suitable bearings. A Upon the shaft,outside the curb, there is a hanged ratchet-wheel.

G is theratchet-wheel, and

His the ange.

`I is the pawl, which is pivoted to the curb, and works in the ratchet, to prevent back motion in the ratchet-wheel. The ratchet-flange is not fast to the shaft.

In a recess in the outside of the `flange H, there is a friction-wheel, J, fast to the shaft.

K represents the crank, which is pivoted to the ange H at l.

It is also connected with the opposite edge of the ange by hook m, which keeps it up to and in Contact with the face of the flange, and also by a spiral spring, n, vwhich has a tendency to draw the crank forward.

The back motion of the crank is limited by the recess and shoulder o, on the edge of the flange, which shoulder the hook m strikes when the crank is drawn back.

So far as` we have described, the windlass could not be revolved by turniug'the crank, as it is attached to the flange H, which is loose on the wiudlass-shaft.

I The wheel J, which is fast on thewindlass-shaft, now comes into use, around which there is a friction-band,A

I, one end of which is attached to the crank at q, and the other end to the recess inthe iange, as seen at fr, the latter of which is a fixed point in the recess,-while the former, or q, moves with the crank. It will be seen that the crank acts upon friction-band l?, by a powerful lever-purchase, the fulcrum beingat l, and the short end of the lever being the distance between qand the fulcrum.

With this leverage, the force of the small spring .n

issufiicient to prevent the wndlass from turning with the Vempty or full bucket, and when the lever is pressed forward, the friction produced on the periphery ofthe wheel J is amply suiiicient to raise the bucket'full of water. For lowering the' bucket, a slight back pressure is given the crank, which loosens the band on the friction-wheel, and allows the bucket to descend as rapidly as may be desired.

The bail is pivoted to the sides of the bucket, so thatthere is but a slight preponderance of weight below the pivots, and so thatV the bucket may be tipped,

when full of water, by a slight exertion of force.

To produce an automatic dischargebf the water from the bucket when the same has been elevated, I place a hook, S, on the inner end of the water-spout E, which catches over the edge of the bucket, and tips it so that the water is discharged into the spout. The hook is hinged to the spout, as seen in the drawing.

T is a curved prong attached to the hook, which Y acts as a guide for the bucket. To insure a proper position for discharging the water, the upper edge of the bucket, on each side of the bail, (when the latter' is in a. vertical position,) is scalloped out, so that the hook will slip on the inclined surface thus produced, and draw-upon the bucket at the bottom of the scallop, and thus squarely tip it.

This method of shaping the top of the bucket is seen in fig. 4, and willbe readily understood from the drawing. There may be a valve in the bottom ofthe bucket for iillingit in the well.

Having thus described iny invention,

I claim as new, and desire to secure by Letters Patent- The combina-tion, with abucket, swinging and emp,- tying-spring, rope, and revolving shaft, of the disk H, dctent I, ratchet G, spring It, lever K, and spring n, all arranged and operating' substantially as described.
